CABLE-RAILWAY SYSTEM.

SPECIFICATION forming part of Letters Patent No. 388,812,dated September4, 1.888.

Serial No. 974,582. (No model.)

To all whom it may concern,.-

Beit known that we, SUMNER A. BEMIs and LoUIs PEINGs'r, citizens of theUnited States, residing, respectively, at Springfield, county ofHampden, and State of Massachusetts, and in the city, county, and Stateof New York, have invented new and useful Improvements in Cable-RailwaySystems, of which the following is a specification.

The present invention relates to improved railways for cable-impelledcars, in which a continuous underground conduit for the cable iscombined with the track-rails; and the invention consists in thecombination and construction of parts, all as will hereinafter morefully appear, and be particularly pointed out in the claims.

Reference is to be had to the accompanying sheets of drawings, in whichsimilar characters of reference indicate corresponding parts in all theviews, and in which- Figure 1 is a plan view of a portion of therailway-structure; and Fig. 2 an end or front elevation thereof, certainof the continuous longitudinally-extending parts being shown in verticalcross-section. Fig. 3 is a horizontal section through the yokes and theconduit shellsections supported thereon, taken at the plane indicated byline 6 6, Fig. 2.

In the drawings, A A represent the carwheel rails, and B one of thetransverse yokes, on a series of which yokes, disposed at suitableintervals, the said rails A and the parts fornr ing the cable-conduitare supported.

Each yoke B consists of a vertical web-wall, a, provided with upper andlower flanges, b c, to give the desired width of bearing-surface for therest thereon of the parts hereinafter mentioned and for its rest on andin the ground. The edges of said yoke are preferably down-Wardly-converging, and are ribbed, as at d, for strength, as desired,and may also be provided with rib-bounded apertures e, the said ribs andapertures permitting a better retention of the yoke in the ground. Theweb-wall a is at its upper central portion cut out in U form, as at g,Fig. 2, the edge of said eut-out part being provided with rightvangledflanges or ribs (i at each side, as particularly seen in Fig. 2, andbetween the vertical web walls e of two properly aligned and distancedyokes is extended a section of the conduit shell D, of suitable metal ormaterial-as, for instance, wrought-iron or boilerplate iron or steel-theends of said shell-section abutting against the face of the web-wall a,and said shell is curved into U shape to conform to the curve of theunder and outer surface of said flanges i, being riveted thereto, asseen at S, and the edges l1, of the conduit-shell ex- 6o tend,preferably, above the upper surface of the yoke.

rlhe longitudinal L-shaped paving-rails E E lie over theupwardly-extended edges lt of said shell,being grooved longitudinallytherefor, as at It, and said pavingrails extend inwardly beyond saidgrooves, and also outwardly therefrom, as at Z, forming bottoniilangerests thereon for their support upon the yokes, being securedthereto, as indicated at m. by bolts 7o and nuts. The bottoms of saidrails E are longitudinally ribbed, as at ra either conti nuonsly or atintervals, and said ribs fit into correspondingly located grooves o inthetop of the yoke.

The vertical portions p of the paving-rails have on theirinner sideshorizontal longitudinal ledges q, on which the lower laterally-extendedends r ofthe slot-rails F rest, said slotrails being vertically extendedto a height, 8o preferably above the top of the paving-rails, and areinwardly danged, as at s, the edges of said flanges being when the saidrails F are in place separated the distance of and form the Walls of thecontinuous slot t, through R5 which the grip may pass, to engage thecable within the U-shaped conduit and travel. Each slot-rail is alsoprovided with an outwardly-extending flange, u, which lies over the topedge of the paving-rail, the top of which 9o flange u is in a coincidentdownwardly and outwardly inclining plane with the top of the flange s,forming a watershed. Between the inside of the vertical portion j) ofeach paving-rail and the opposing vertical face of the slot-rail F areblocks or beams G, of wood or other similar slightly-eompressiblematerial, and bolts w are passed horizontally through thc thickness ofthe vertical portions of the paving-rails and slot-rails and through thein- Ioo terposed yielding material, thereby firmly clamping andconfining thesaid parts. Indiarubber in any of its elastic compounds mayin some instances advantageously constitute the yielding interposingmaterial.

rl`he track-rails A rest in suitable chairs formed on or attached to thetop of the yoke at their outer portions.

Brace-rods M are provided at suitable intervals extending between thetrack-rails,and the pavingrails being bolted thereto in any suitablemanner, and tend to hold same in their proper positions and relations,and the horizontal parallel disposition of the pavingrails is madepositive and constant by the interlocking of theribsn thereof with thegrooves o in the top of the yoke, and said pavingrails and the yokesimmovably attached form the structure from which the other parts aresupported and held in their proper positions.

As Will be seen in Fig. 2, the flanges i are shown as extending from theupper end portions of the U-shaped shell D to and ending at a littledistance from the median line ofthe shell, as at 40, so that anunobstructed space is left in the bottom of the conduit at its inside asdesirable for various purposes, such as to permit of an effectivesweeping or clearing of the conduit.

The yoke B is preferably cast in two sections, as seen at each side ofthe line 30, Fig. 2, a flange-rib, 3l, at the abutting portion of eachsection being formed thereon, through which the bolts are passed foruniting said sections as one. The twopart formation of the yokepossesses important advantages, of which may be noted that an economy oflabor is thereby secured; that the half-sections may be cast more nearlyperfect than when the yoke is integrally cast; that,should the yokebecome broken at one side portion, such portion simply may be replaced,the other being left in tact; and that in reaching adjacent gas, water,Sewer, or other conduits, for repairs, &c., it may be found onlynecessary to remove one side of the yoke, the traffic at such time notbeing necessarily interfered with.

Brackets N may be integrally formed on the yokes either at their edges,as shown, or disposed Within the apertures e for the support of aconduit, P, for inclosing electrical conductors.

The edges of the conduit-shell D, extending above the plane of the topof the yoke and into the longitudinal recess k in the pavingrail, affordincreased means for maintaining the said shell D immovably in place andagainst warping and prevent the entrance thereto of dirt, &e., fromunder the said paving-rail, and the relative formation and arrangementof the slot and `pavingrails with the interposed thickness ofeompressible material G performs a similar dirt -excluding service, andalso enables, due to the compressiblc nature of said interposedmaterial, a nice adjustment of the slot-rails on the supportingpaving-rails, so that the slot t may be kept of uniform width.

The dotted lines Q indicate the grade or paving plane, and it will benoticed that all the bolts for adjusting the slot-rails arc near suchgrade-surface and easily reached.
